3. If more than one
polyatomic ion, put it in ( ) and then tell how many as subscript after ( ).

4. Covalent bonding
holds the polyatomic ion together.

NaNO3 =
sodium nitrate

Mg(OH)2
= magnesium hydroxide

Ba(NO3)2
= barium nitrate

Ca(HCO3)2 = calcium
hydrogen carbonate

(IUPAC System)

or

calcium bicarbonate

(Classical System)

Type II c

Metal + Polyatomic
Ion

(Metal has
more than one type of charge)

1. Name the cation
(metal) first but follow rules as listed in Type II above.

2. Follow rules as in
Type III a. If more than one polyatomic ion, put it in ( ) and tell how
many as a subscript after ( ).

3. This is ionic
bonding between metal and polyatomic ion.

4. Covalent bonding
holds the polyatomic ion together.

Cu2SO4
= copper (I) sulfate (IUPAC System)

or

cuprous sulfate (Classical System)

Ni3(PO4)2
= nickel (II) phosphate

(IUPAC System)

or

nickelous phosphate(Classical System)

Type II d

Polyatomic Ion +
Polyatomic Ion

(NH4+
= ammonium ion)

1. Name polyatomic ions
as memorized.

2. Place ( ) around
polyatomic ion ONLY IF more than one, then tell how many as subscript
outside ( ).

3. This is ionic
bonding between metal and polyatomic ion.

4. Covalent bonding
holds the polyatomic ion together.

NH4ClO=
ammonium hypochlorite

(NH4)2SO3
= ammonium sulfite

Type II e

Polyatomic Ion +
Nonmetal

1. Name polyatomic ion
them nonmetal,

2. Nonmetal name is
changed to the “ide” suffix since it is the anion.

NH4F =
ammonium fluoride

(NH4)2O
= ammonium oxide

Type III

Nonmetal + Nonmetal

1. Name as though ionic,
even though it is not. This is covalent bonding.

2. Do not try to
solve using metal + nonmetal rules. JUST NAME IT USING GREEK PREFIXES.

mono =1, di=2, tri=3,
tetra =4,

penta =5, hexa =6, hepta
=7, octa =8, nona =9 deca =10

3. Never use mono for
the first element.

SO3 =
sulfur trioxide

P2O5
= diphosphorus pentoxide

Acids & Bases

1. Acids have H written
first in the formula. These are the transferable hydrogens. Acids should
be denoted by the (aq) state. Acids without oxygen are named hydro___ ic
acid. Acids with oxygen are named by looking at the ending of their
polyatomic names. If “ate”, then “___ic acid” and if “ite”, then “___ous
acid”. Hydro is not used with acids with oxygen in it.

2. Bases can be easily
recognized when the hydroxide ion (OH-) is observed. Ammonia (NH3)
is also a base.
